Application filed April 13, 1909. I Serial No. 489,682.

To all whom it may concern:

end of a shaft 4: "carried by the frame 2.

Be it known that we, HOWARD R. Mc- The shaft t carries at its opposite end a Ninnn and JAMES CLEMENT, citizens of the .United States of America, and residents of Buffalo, in the couhty of Erie and State of New York, have invented certain new and useful Improvements in Stave-Jointing Machines, of which the following-is a full. clear, and exact description.

Our invention relates to machines for jointing staves and by means of it s taves may be prepared for tanks, vats, stills, barrole and other regularly ta ered receptacles in a manner to*give the (esired longitudinal taper and the necessary bevel to the edges of the staves.

The operations just described performed by the machine on the stave, are performed simultaneously. j

Our invention isso designed that-it is adapted for properly beveling and taperin staves which may very largely in size an the machine may be adjusted for operating on staves of various widths, lengths, thicknesses, and various degrees of taper.

Our invention contemplates the use of means for feeding staves to be jointed and holding them in position for jointing; meansfor jointing the staves. so that they will be of tapered form and likewise means for beveling the joints at any desired angular bevel. v

Our invention is simple in construction and operation and is very efficient in its action upon the staves to be jointed.

The many advantages and other objects than those above stated of our invention will appear from the following description and the novelty of' the invention will be.

pointed out in the claims.

Referring to'the accompanying drawings 'in whichlike letters of reference indicate corresponding parts in all the figures, Figure 1 is a top plan view of our invention. Fig. 2 is a side elevation of the "same. Fig. 3 1s a section taken on the. line A-B of Fig. 2.

Power for operating the machine is applied by belt or otherwise upon the power ,wheel 3 which is suitably journaled on one sprocket wheel 5 but of course it is to be understood that some other suitable means of transmitting power may be used in place of this sprocket wheel. Another sprocket wheel 6 is suitably mounted on a shaft 7 also carried by the frame 2. This shaft 7 carries at one end a bevel gear 8 and at its other end a similar bevel gear 9. A sprocket chain 10 engages with the teeth of the sprocket wheels 5 and 6 and thus power is transmitted from the power wheel 3 to the ed on the shaft 14 and journaled in the frame 2 at the opposite end of the machine.

A friction'clutch 15 is mounted on the shaft 14: and the drum 13 may be thrown into and out of contact with it 'by means to be hereinafter described. A corresponding frieti'on clutch 16 is mounted on the shaft 12 and thiegdrunr 11 may be thrown into and out offe ngagement with it by means to be hereinafter described. The outside faces of the friction clutches 15 and 16, are provided with bevel gears 17 and 18 which mesh with the bevel gears 8 and 9 on the shaft 7 ,in such a manner that the friction clutches 15 and 16 are rotated in opposite directions.

A cable or rope 19 has one of its ends secured on the drum 11 and its opposite end secured on the drum '13 so that-it is drawn comparatively tight between these two drums.

on the shaft 21. This shaft is riven by means of a belt 22 passing around a pulley 23, the latter being also carried by the said shaft 21 (see Fig. 3). This shaft 21, saw 20, and pulley 23, are carried by a'longitudi- .nally movable carriage 24 which moves on and bear upon the under side of the guide- IA circular saw '20 is suitably gournaled ways 25 and 26 3).

Thus these L- shapedplates form glbs for the carriage 24 and hold same down upon the gu1de-ways25 and 26. The stops 27 and 28 carried bythe rod connected at one end with the arm 32 of a bell crank lever 34 and at its opposite end is pivotally connected with the arm 33 of a bell crank lever 35 (see Fig. 2). The bell crank lever 34 is fulcrnmed at 36 in a hearing 37 carried by one of the standards 1. The bell crank lever 35 is fulcrumed at' 38 to a suitable bearing 39 carried by another of the standards 1.

Rotatably mounted on suitable bearings 40 and 41 is a rod 42 to which are rigidly secured levers 43. Bars 44 are pivotally connected with levers 43 and placed in engagement withthe arms 45 and 46 of the bell crank levers 34 and one of the arms is in its lowermost position, the other is 111 its uppermost position. Each of the drums 11 and 13 are provided with clutch collars 83 which carry pins 47 which are engaged by the bifurcated ends 48 of levers '49. The levers 49 are pivoted at 50 at some suitable place on the frame 2 and the lower ends of these levers are slotted at 51, through which slots the bars 44 pass. Each of the bars 44 is provided with a notch 44 sothat when the inner ends 52 of the bars 44 are allowed to fall downwardly. the notches 44 engage with the lower ends of the levers 49.

- Suitably secured to the rod 42 are (tastings 53 having slots within which spiral springs 54 may be placed Rods 55 pass tlnough the upper parts of the castings 53 and extend beyond the lower ends of the spiral springs 54 where they are secured. The other ends of the rods 55am pivotally mounted on the ends of the clampingframe 56 by means of the pins 87. Thisfranle 5G is carried between the standards 57 and 58 and the angle plates 84.

the bearing ends of the frame 56 are adapted.

to have a slight vertical movement.

' The legs of the angle plates 84 are each provided with a vertical slotin which the/pins 87 move. ,Preferably to theouter ends of the pins 87, which are fixed to the ends of the frame 56, are secured suitable The arms 45 and- '46 ust mentioned are so connected that when spiral springs 61 and 62 the other ends of which are secured to bolts or other supports 63 standards 57 and 58. springs 61 and 62 is to hold the clampin frame 56 in its uppermost position. Carriec' by the lan'1ping frame '56 and passing through it are a series of two or more clamping bolts 65 which extend any desired distance below the lower surface of the clamping frame, which distance is regulated by means of the nuts clearly shown in Fig. 2.

The carriage 24 which is guided in its longitudinal travel by the gulde-ways 25 and 26 moves transversely on said-guide-ways and its transverse movement is controlled by the guide plate 66 which is secured to the frame 2 and which passes through the slot 89 provided on the under side of the carria 2-1. This guide plate is made of flexible metal through which are passed a series of adjusting bolts 67 and 68-. The bolts 67 are screw-threaded through the guide plate (56 and their ends strike against the plate 69 carried by theframe 2. The bolts 68 are carried by the plate 69 and pass through the guide plate ()6 and are there secured-by suitable nuts. By means of this arrangement the guide plate (56 may be bent into any desired curve or kept in a substantially straight and 64 carried by the upper ends of the The tendency of the line. As shown in Fig. l the guide plate 66 is bent in substantially the outline of one side of a tapered stave and as the-carriage 24 carrying the saw 20 travels longitudinally on its guideavays 25 and 26 it will travel likewise trans\-'ersely as. it is guided in its longitudinal travel over the guide plate 66.

Carried between the standards 5'7 and 58 is a feeding table 70 at one end of which is a slot 00 in which a stop or gage 91 is adjustably fastened by any suitable means. The supports 71 which carry the tilting rests 81 are provided with slots through which bolts 72 pass and these bolts are clamped in place through said slots by means of. nuts or in any other suitable way. The tilting rests 81 carried by the supports 71 may be adjusted so that the said rests 81 can be inclined at any desired angle. The stave 82, which is to be jointed, is placed upon the feeding table '70 and the tilting rests 81. Obviously thebevel of the edges of the staves will be determined by the angle at which the tilting rests 81 are adjusted. Below the feeding table 70 and 'between the standards 5'7 and 58 is rotatably mounted a gage 73 its bearings 74 being carried by the frame 2. The gage 73 carries thegagearms 75 and '76 at the upper ends of whichare handles 77 and 78 by means. of which the material to be sawed into stares may he put into its proper position relative to" the saw 20 after one side of the said material hasbeen acted upon by said saw, Rigidly secured to the rod '42 is a treadle 79 which may be depressed by the operators foot The bolts 65 on the clamping frame 56 are initially adjusted so that when the frame '56 is moved downwardly the bolts 65 will clamp against the stave which is to be jointed and hold it firmly in place.

Having thus described the several partsof our invention we will now describe its method of operation.

The tilting rests 81 supported 'by feeding table 70 are first'adjusted to the angle which will make the desired bevel on the edge of the stave to be formed. The stave 82 which is to be jointed is then laced upon the tilt ing rests 81 and the feeding table 70. Power is applied to drive the belt 22 thus rotating the saw 20 and likewise power is applied to the power wheel 3 thus rotating the sprocket wheel 5, the sprocket wheel 6, and the shaft 7 carrying the bevel gears 8 and 9. Thereby the friction clutches 15 and 16. are oppositely revolved as previously described. The operator then presses his foot upon the treadle 79 and the first effect of that movement is to pull downwardly the rods 5.5 thus carrying downwardly the clamping frame 56 so that the bolts, 65 clamp the stave 82 in proper position for being acted upon by the saw 20. A further depression of the tread-1e 79 causes the levers 43 to be moved so that the 'fiotch 44 in one of the bars 44 comes in engagement with the lower end of the lever 49. By this engagement the lever 49 is re tat-ed on its, fulcrum 50 so that its bifurcated end 48 engaging with the pins 47 throws one of the drums 11or 13 in contact with one of the friction clutches. 1 5 or 16. The bevel gears 8 and 9 bein constantly in mesh with the bevelgears 1 and 1 8 of the friction clutches 15 and 16 whether these clutches are in contact with thedrums 11 and 13 or not, it will be evident that when one of the drums is thrown into contact with one of the friction clutches-.ihat drum will thereby be rotated.

As previously stated, when one of the arms 45 or 46 of the bell crank levers 3:4 or 85 is in its lowermost position the other arm necessarily is in its uppermost position. Therefore, when the treadle 79 is depressed sufliciently to. throw the notch 44 of one of the bars 44 in contact with the lower end of the lever 49 the other COIIQSPOIldlH notch of the similar lever will be raise 'sufiiciently high so that it "will not engage with the lower end of the other lever 49 The result, therefore, of this depression of the treadle 79 will be to, throw one of the drums 11 or 13 into engager'nentwith only-one of" the friction clutches 15 or 16.

Assuming that the operation ust described I will throw the drum 11 into contact with the friction clutch 16 this drum will be rotated so that the. cable' or rope 19 being secured at to the carriage 24 will draw the carriage cameo 24 longitudinally to the right of Figs. 1 and 2. The carriage 24 having both a longitudinal and transverse movement as already explained will move on the guide-ways 25.

uppermost position and simultaneously the bell crank lever 35 will be thrown so that its arm 46 is in its lowermost position. The re sult of this operation will be to raise the end 52 of the bar 44 which is at the right of the machine and throw its notch 44 out of engagement with the lower end of the lever 49,

,thereby throwing the drum 11 out of contact with the friction clutch 1(5 and thus stopping the rightwise travel of the car- This will throw the .bell crank lever 34 so that its arm 45 is in its riage 24; at the same time the end 52 of the bar 44, which is at the left of the machine, is lowered so that it rests upon the bottom of the slot 51 of the lever 49 and is in a position to have the notch 44 fall into engagement with the lower arm ofthe lever 49 when the treadle 79 is released from the pressure of the operators foot.

\Vhcn the carriage 24 has reached its maximum right hand travel the t1eadle'79 is released, which allows the clamping frame 56 torise, thus releasing the stave which may be reversed and put into position to have the other side operated upon by the saw 20. When the stave has been reversed and placed against the stop or gage the treadle 72 is again depressed which again clamps the stave upon the feeding table 70 and the tilting rests. 81. A further depression of the-treadle "79 causesthe notch 44 win the bar 44 Which-is. at the left of the new chine to rotate the lever 49 on its fulcrum 50, thus throwi-ng the bifurcated end 48 of the lever against the pins 47. which are secured to the'clutch collar 83. so that the drum 13' carriage 24 both longitudinally and transversely is identical with its opposite travel as previously described. Thus it willbeunderstood that there is no idle return stroke,

but that the saw 20 is made to operate upon" the stave when the carriage 24 travels from left to right or from right to left. The saw 20 of course runs constantly in the same direction of i'otation, the only difference be ing that the sawdust is thrown downwardly when the carriage travels in one direction and when traveling in the opposite direction the sawdust is thrown upwardly. Should the momentnn'i of the travel of the carriage 2st to the right or left of the machine be sufficient to carry it beyond the stops 27 or 28 the carriage will be stopped by the flanged ends 31 of the springs hen the carriage has reached the limit of its leftwise travel it strikes the stop 28 which thus re verses the positions of the bell crank levers 34 and and puts the bars 44 in position to throw the drum 11 in engagement with its friction clutch 16 when the treadle 79 is again depressed.

By means of the mechanism operated described it will be evident that states of any desired bevel, width, length, thickness and taper can be easily, cheaply and quickly jointed in our machine. Manifestly it is not necessary to drive the friction clutches l5 and 1G by the specific means herein shown and described. Instead of using the sprocket wheels 5 and 6 and the bevel gears 8 and 9 together with the beveled faces 17 and 18 power can be directly applied to shafts 12 and 1.4: and identically the same results be thereby accoi-nplished. It is therefore to be understood that tlme embodiment of our invention as herein shown and described only shows its preferable construction and we do not Wish to be confined tothe exact details of construction herein shown, since it will be evidentto those skilled in the art that various inodilicati ms of these details can be made without de 'arting' from the spirit of the invention.
